Gotta love the patent pipeline! Now imagine you could press a button and just cut off the caller on the other end – politely. The Driver-Attentive Notification System enables a driver to purposefully inform a remote caller to reduce the conversation intensity level for a moment while facing an attentive condition (read: It tells callers to shut up for you). When needed, the driver can press a switch that automatically sends a notification message to the remote caller.
This kinda sounds like something that is on the market now: The end call button.
